I don't believe the 160db without photos of the vehicle and an official DB Drag / Extreme SPL rating. People I know who do DB Drags have no time for car puters, 150db and up vehicles are built for one purpose and one purpose only, sound. They don't waste their time with any "frills" in the vehicle.

FYI: Here is mine, (before I turned it into the Fallen Heroes Car with a redesign) and my SSD has zero issues in the car.
